Abstract

Ein Durchflussmengenmesser (1), insbesondere für Warmwasserheizungsanlagen, umfasst ein Messteil (2) sowie ein Anzeigeteil (3). Das Anzeigeteil (3) besteht aus einem Grundkörper (11) mit einem in das Sammelrohr (4) hineinragenden zylindrischen Teil (17), in dem eine mit einem Prallteller (10) in das Messteil (2) hineinragende Anzeigestange (9) längsbeweglich ist. Erfindungsgemäß ist dem Prallteller (10) in Durchströmrichtung des Heizmediums ein Sieb vorgeschaltet. Wenn sich der Grundkörper (11) in ein die Anströmung des Pralltellers (10) beeinflussendes zylindrisches Ansatzteil (17) fortsetzt, ist zweckmäßig der untere Teil (18) des Ansatzteils (17) in seiner zylindrischen Außenwand mit einer Anzahl von über seinen Umfang verteilten achsparallelen Schlitzen (21) versehen. Hierdurch werden Schmutzpartikel, welche die Funktion der Anzeige beeinträchtigen könnten, weitestgehend zurückgehalten.

A flow meter (1), in particular for hot water heating systems, comprises a measuring part (2) and a display part (3). The display part (3) consists of a base body (11) with a cylindrical part (17) projecting into the collecting pipe (4), in which a display bar (9) projecting into the measuring part (2) with a baffle plate (10) is longitudinally movable. According to the invention, the impact plate (10) is preceded by a sieve in the flow direction of the heating medium. When the base body (11) continues into a cylindrical attachment part (17) influencing the flow of the baffle plate (10), the lower part (18) of the attachment part (17) is expediently provided in its cylindrical outer wall with a number of axially parallel axes distributed over its circumference Slots (21) provided. As a result, dirt particles, which could affect the function of the display, largely retained.
